Phosphor coating lines the inside of fluorescent light tubes. When the gas inside the tube is excited by electrical current, it emits ultraviolet (UV) light. The phosphor coating then absorbs the UV light and re-emits it as visible light, creating the glow from the fluorescent light.
Phosphor is the material that lines the tubes of fluorescent lights and glows when exposed to UV light. This material emits visible light when excited by ultraviolet radiation.
No, fluorescent materials typically do not glow under infrared light. Fluorescent materials absorb ultraviolet or visible light and then re-emit light at a longer wavelength, usually in the visible range. Infrared light is outside this range and does not stimulate fluorescence in these materials.
Certain foods that contain fluorescent compounds, such as tonic water, certain types of fish, and some types of cheese, can glow under a black light.
Laundry detergents that contain optical brighteners, like Tide, Seventh Generation, and Persil, may glow under a black light due to the presence of these fluorescent compounds. However, not all detergents with optical brighteners will necessarily glow.
modern day glue glows under UV however old glue (animal bi-product) will not. You can use blacklight to detect modern day repairs in everything from furniture to pottery and everything in between that could be fixed with glue.
Phosphor is the material that lines the tubes of fluorescent lights and glows when exposed to UV light. This material emits visible light when excited by ultraviolet radiation.
The material lining the tubes of fluorescent lights is called a phosphor coating. This coating is designed to emit visible light when excited by ultraviolet (UV) light produced by the electrical discharge within the tube.
The interior of fluorescent light tubes are coated with a phosphor material. When this phosphor material is excited by ultraviolet light produced by the electric current passing through the tube, it emits visible light, creating the glow that we see.
An incandescent light uses electric current passing through a wire with a high resistance to current flow. That makes the wire very hot and it glows, producing the light. A fluorescent light uses electricity to charge a gas in a tube. The charged gas glows, producing the light. For the same amount of light, more electricity is needed in an incandescent light than in a fluorescent light, but developing and building fluorescent lights required more advanced technology than did incandescent lights.
No, fluorescent materials typically do not glow under infrared light. Fluorescent materials absorb ultraviolet or visible light and then re-emit light at a longer wavelength, usually in the visible range. Infrared light is outside this range and does not stimulate fluorescence in these materials.
when it glows under ultraviolet light.
Chemical energy (chem-lights and lightning bugs) electricity (through LEDs, fluorescent tubes, neon lights, lasers) and heat (the sun glows from heat, and so do light bulbs)
Fluorescent material immediately glows when exposed to ultraviolet radiation, that is it fluoresces. Phosphorescent material slowly absorbs and re-emits the radiation it absorbs. This enables phosphorescent material to absorb visible light spectra to "glow in the dark" at a later time.
it is plasma , gas and liquid

If you put them under ultra-violet light it changes color and glows.
Compact Fluorescent Lamp lights are a popular bulb alternative used today. Its advantages include a much longer lifespan that an incandescent, and it glows a more relaxing light towards the eyes.
